A 192-unit Boston mid-rise apartment complex known as Castle Square Apartments is slated for the largest Deep Energy Retrofit ever undertaken in the U.S.
The renovation of this South End affordable housing development will be made possible, through $6.7 million in funding from the U.S. Department of Housing and Urban Development’s Recovery Act Green Retrofit Program. The retrofit is expected to cut the development’s energy use by 72 percent.
A new, super insulated shell – combined with a super insulated reflective roof, high efficiency windows and extensive air sealing – is expected to increase the building’s insulation value by a factor of 10. This will allow Castle Square to maintain a comfortable indoor temperature using a fraction of the energy it currently consumes for heating and cooling (along the lines of the Passive House model).
The project will supply residents with additional energy savings via high efficiency cooling and heating equipment, LED and CFL lighting, Energy Star appliances and solar hot water. Residents will remain in their apartments during construction, which is expected to be complete by March of 2012.
